  • GPS and data from other navigational equipment is transmitted over a digital data network, preferably a fiber optic network, that is provided in a vehicle for distributing data among the various electronic devices on-board.
  • Voice and data streams sent to, and received from, wireless networks operating in the area, e.g., a WWAN, WLAN or WPAN, are also distributed over the fiber optic network for use by various on-board devices.

  • one passenger may be watching a television, video monitor or display device (121) that is connected (125) to the data network (100) and receives an appropriate video or audiovisual signal there from.
  • another passenger may be listening to an audio program through a set of headphones (122) that are connected (124) to the network (100) and receive an audio signal there from.
  • the network (100) can carry digital data in any format. Consequently, the network (100) maybe carrying, for example, a DVD audiovisual data stream; and/or an MPEG-1, MPEG-2 or MPEG-4 audiovisual data stream; and/or a Motion JPEG or Video CD (VCD) audiovisual data stream, and/or a CD audio data stream, and/or an MP3 audio data stream, etc.
  • the network can also carry multiple data streams simultaneously.
  • the network will have to carry data in a format useable by the various output devices, or those output devices will have to be connected to the network with an interface that translates the incoming audiovisual data stream into a form useable by that output device.
  • audiovisual output device or “output device” refers to any device that renders an audiovisual signal or data stream perceptible, visually or aurally, to a human user.

  • Fig. 2 is a block diagram of an antenna farm for a GPS receiver and wireless network transceivers that are interfaced with the in-vehicle data network (100) according to the principles of the present invention.
  • the present invention preferably includes an antenna farm (125).
  • the antenna farm (125) preferably includes a GPS receiver (113) with an antenna (111).
  • this GPS receiver (113) receives transmissions from a number of orbiting satellites via the antenna (111). With the data from these transmissions, the receiver (113) can determine its physical location in the world, usually in terms of longitude and latitude, and, perhaps, altitude.
  • the GPS receiver (113) may receive data from 24 satellites circling the Earth. This data is converted to National Marine Electronics Association (NMEA) standard data packets. These data packets are transmitted to an appropriately programmed micro-controller (106) that reads the data and can determine from the data the vehicles' latitude, longitude, heading, speed, etc.
  • NMEA National Marine Electronics Association
  • this supplementary navigational equipment may be an inertial sensor stage (112).
  • the inertial sensor stage (112) may include an altimeter, odometer reading, speedometer reading, gyro, accelerometer, wheel speed/direction sensors, digital compass, etc.
  • the digital compass of the inertial sensor obtains vehicle-heading information from a circuit that detects the Earth's magnetic field.
  • This heading data is also provided to the GPS receiver or the micro-controller (106) and is used to check or replace the heading data provided by the GPS receiver (113) if the vehicle is moving too slowly for the data from the GPS receiver (113) to provide an accurate vehicle heading indication.

  • Fig. 2a may also be considered as a diagram for software or programming run by the micro-controller (106) when utilizing data from the GPS receiver (113) and the inertial sensor stage (112).
  • the micro-controller receives data from the GPS receiver (150). With this data, the micro-controller assesses the speed of the vehicle (151). The micro-controller may also receive data from the vehicle speedometer to determine vehicle speed. Below a predetermined speed, the GPS data will be considered as providing an unreliable indication of the vehicle's heading (152).
  • the GPS data will be used to determine the vehicle's latitude, longitude, heading, etc. (153). Alternatively, if the speed is low enough to render GPS heading data unreliable, data from the inertial sensor will be used to determine heading (154). The GPS data will be used to determine the vehicle's latitude and longitude (155).
  • data from the GPS receiver can also be used to improve the performance of the inertial sensor.
  • the GPS receiver can improve the accuracy of the inertial sensor by indicating geographically where the inertial sensor is.
  • the inertial sensor in a vehicle is initially calibrated based on where the vehicle is sold. This is done by manually entering a declination zone number for the declination zone in which the vehicle is sold. A correction factor for the inertial sensor is automatically associated with the indicated declination zone.
  • the inertial sensor will no longer be properly calibrated and will, therefore, be inaccurate. This inaccuracy can amount to as much as 30 degrees if, for example, the vehicle is driven across the continental United States. Because this need to calibrate the inertial sensor is not well known and is usually performed by sales staff before a vehicle is purchased, the vehicle may be moved into another declination zone, perhaps permanently, without the inertial sensor being properly re-calibrated.
  • the GPS receiver (113) can always determine its latitude and longitude. This will also indicate in which declination zone the GPS receiver (113), and the inertial sensor (112), are located.
  • Fig. 2b illustrates this use of the GPS data to calibrate the inertial sensor stage (112).
  • Fig. 2b may also be considered as a diagram for software or programming run by the micro-controller (106) when utilizing data from the GPS receiver (113) and the inertial sensor stage (112).
  • the micro-controller receives data from the GPS receiver (160).
  • the GPS data specifies or is used to determine the latitude and longitude of the vehicle (161). It can then be determined if the vehicle has moved from the original declination zone into another (162). If no such movement has occurred, the current calibration or correction factor for the inertial sensor is maintained (163).
  • a new correction factor for the inertial sensor is identified (164). This may be done through a look-up table available to the micro-controller or other means. This new correction factor is then applied to the data output by the inertial sensor (165) to obtain an accurate vehicle heading.
  • the micro-controller (106) can make that information available to other devices over the digital network (100).
  • the navigational data (127) can be transmitted from the micro-controller (106) to the data format stage (107) where the data is formatted for transmission over the network (100) and for use by other networked devices.
  • the micro-controller (106) then sends a control signal (105) to the network interface stage (101).
  • the network interface stage (101) also receives the formatted navigational data (103) from the data format stage (107).
  • the network interface stage (101) then transmits that formatted navigational data over the in-vehicle data network (100).
